There are usually no more than four trophic levels in a food chain. Why?

• Energy gets lost (metabolism) and too many links cannot be supported.

• Energy is gained (metabolism) and too many links cannot be supported.

• There are not very many animals on earth.

• Stays the same

• Decreases

• Increases

If a farmer does not till (plow their fields), which of the following would be the most likely result.

An energy pyramid shows the loss of energy at each trophic level. Why is energy not really lost?

• Some energy is converted into waste and heat energy.

• Some energy goes back to the sun.

• Some energy is recycled.

• All energy gets transfered to the next organism.
